Monosized beads of polar resins were synthesized for combinatorial chemistry and chemical biology by sustainable microchannel flow synthesis. Regular, biocompatible, and optically encoded beads could be efficiently prepared on large scale and in high yield. In a preparative flow polymerization instrument, taking advantage of a designed T-connector for droplet formation, quality beads were synthesized with accurate size control using a minimal amount of recirculating silicon oil as suspension medium. Bead-size was controlled through shear imposed by the silicon oil flow rate. This process provided 86% yield of ∼500 μm macrobeads beads within a 20 μm size range with no deformities or vacuoles, ideally suited for combinatorial chemistry and protein binding studies. The simple flow equipment consisted of a syringe pump for monomer and initiator delivery, a T-connector, a gear pump for oil recirculation, a long, heated coil of Teflon tubing and a collector syringe. The method was used for preparation of PEGA1900 beads, optically encoded with fluorescent microparticles. The microparticle matrix (MPM) encoded beads were tested in a MPM-decoder showing excellent recognition in bead decoding.

组合化学和化学生物学编码珠的可持续流合成

通过可持续的微通道流动合成,合成了极性树脂的单个珠粒,用于组合化学和化学生物学。规则的,生物相容的和光学编码的珠子可以大规模,高产量地得到有效制备。在制备型流动聚合仪中,利用设计的T型连接器来形成液滴,使用最小量的循环硅油作为悬浮介质,通过精确的尺寸控制合成了高质量的珠子。通过硅油流速施加的剪切力来控制珠粒的大小。此过程可在20μm大小范围内提供86%的〜500μm宏观珠子收率,没有畸变或液泡,非常适合组合化学和蛋白质结合研究。简单的流量设备包括用于单体和引发剂输送的注射泵,T型连接器,用于油循环的齿轮泵,特氟龙油管的长加热线圈和收集器注射器。该方法用于制备PEGA1900个珠子,由荧光微粒光学编码。在MPM解码器中测试了微粒基质(MPM)编码的珠子,该珠子在珠子解码中表现出出色的识别能力。
